TQ ALL WHOM IT MAY CONCERN:

Be it known that I, D. 'J'. M RTIN, of Covington,.0hio have invented .certain new -and useful-improve-4 ments ^in.Animal-Traps; and I declare the following to lbe a full, true, aixd exact. description of the same', reference being had tothe accompanying drawings, and-to the letters of reference marked thereon. I

Figure 1 represents 'a perspective view of my trap. I

Figure 2 represents a section view of the same. Letter A represents the frame of my trap, which is so constructed as to be divided into an'upperV and a lower compartment, (as shown in fig. 2,) and is also provided with a glass top, which is securely held in its place by the greoved cap pieces B B. Letter C represents an apronor platform, which extends to some distance beyond the front end of the trap, and is provided for the purpose of ,allowingthe animal to get a view of the' bait, which his placed on the inside of thc trap. Letter D represents the door, whicl'i is p'lacedtituhel -front end of the trap, p `and is `held in its place by and works in the grooved uprights E E. This door r'nay bc constructed of any` desirable material.- Letter F represents a catch, which is fastened to one side of-the frame A, and should be made of` spme'springymaterial, sothat when it, is drawn back for the purpose of allowing the door D to fall, as soon as the door is raised again it should spring hack fur enough to allow the door to rest upon its shoulder and to prevent it from closing. Letter G (iig. 2) represents a treadle, which is placed in the rear-ofthe platf2I Q1Lad.S.C,Q1lDeCCd with, the catch I" ,by means of .the cor.d.ll., .ll l1is.platferm ,isso constaucted .a'sioform a troughfor the purpose of holding the meal or bait, and is so balancedupon pivots that the slightest pressureV fpon 4its-l' front part will cause it to tilt downwards. Letter I repnesent's another tilting platform, which is .placed immediately in the rear of but is -larger than the first one, and is also balanced upon pivots. The front end of this platform rests upon the support J, and is provided with a small weight, L, suilicient to overcome the balanee'of the other end, and to retain it in its place. The 'rear end of the trap is closed sullciently by ineensl of the-upright wires M to prevent an animal from escaping, and is open enough to allow `the light to'enter freely. .Connected withtthe platform I is the arml N in such away that when the platformis tilted, eitlrer up or down, it causes the anm to move backwards and forwards. Letter O represents a. double crank, (as swhown in iig. 1,) one arm of which is connected with the arm N, by`means of the cord P, and the other end is conf n ected with the door D hyrmeans of the cord R.- This crank is placed upon tho top of the front part of the Vt'rap. "'The modus opeaadis as follows: The bait is placed upon the treadle G, and the door raised high enough to allow it to rest upon the shoulder of the catch F. The trap is now ready for use. 'lhc animahjumps upon the platform C, and seeing the bait upon the inside'of the trap ventures in. As soon ns his weight presses upon vthe treadle G it tilts downward, drawing' the caltch F from under the door, by means of the cord H, when the door immediately falls and the animal iscaged. Seeing light in the back end of the trap, and an apparent way of escape, he seeks an exit there, but as soon as he reaches the rear end of the platform I it tilts 'down- Yards and precipit'at'es him intothe lower compartment, when the weight L causes it to fall buck into its proper positiomA LIn tilting downwards the arm N is` drawn back, which tightens the cord P suilciently to raise thev door D, 'by means-of' the double' crank 0, high enough to again catch up the shoulder of the catch F, when the Atrapis, lagain V set and is ready fortlie'neet animal that comes. Thus cach animal sets the. trap for the other. Having thus'described myihventem, what I claim, anddesire to secure by Letters Patent, is-

t. 1 `The employment of the springitrigger or catch F for the purpose of engaging the sliding-door D, in the .manner specified.' l 'l' i I 2t .comhinationwith the abovey I claim sliding-door D, cord 4H, treadle G, substantiallyas und for the fpnrpose described. I l In -testimony whereof I set my hand in presence of two witnesses. i l
